Eikenella corrodens prosthetic valve endocarditis in a patient with ulcerative colitis

A 33-y-old male with ulcerative colitis developed prosthetic valve endocarditis (PVE) caused by Eikenella corrodens. The outcome of conservative treatment was successful. Only 2 cases of E. corrodens PVE were found in a survey of the English-language medical literature. In contrast to previous data indicating that eikenella infections usually derive from the oral cavity, our patient most likely acquired the infection by colonoscopy and mucosal biopsies, which were performed a few days before onset of the disease.
